Abstract

The use of viscous CFD simulations to evaluate the resistance of ships is well established. These methods, however, often require a high number of calculation cells with consequent substantial hardware requirements. The objective of this paper is to standardize the operating modes to perform viscous simulations with a rational approach basing on a lower number of cells, for carrying out more rapidly the calculations, without super-computers. This operating mode will be supported by the study of different hulls, displacement and planing, to evaluate a system of localized mesh-sizing of the computational grid that could be standardized for each type of examined hull and to define a protocol to get a good simulation in the shortest time possible.
